PostSubject: Round Robin (Stockfish 8, Komodo 10.2, Houdini 5) Tournament with long thinking time by Stefan Pohl    Wed Dec 14, 2016 4:42 pm

Hardware: i7-6700HQ (2.6 GHz) Notebook (Quadcore), Windows 10 64bit, 12GB RAM
Fritzmark: 4 cores / 8 threads: 21.01 / 10084 (CPU-speed reduced to 99% (to switch off the Intel Turbo Boost))
Hash: 4 GB per engine
GUI: Fritz 13 GUI (no draw, no resign)
Tablebases: None for the engines, 3-5 Nalimov for GUI
Openings: My new 10 moves SALC V2.0 opening-book. Download it at the Downloads & Links section.
Ponder, Large Memory Pages: Off
Thinking time: 24'+5'' per game/engine (average game-duration: 60', so around 25 games per day are played). Average thinking time in the middlegame is around 45'' per move. Stockfish 8 calculates around 6.5 meganodes per second in early middlegame (with 8 threads). So the played games are high-quality-chess.
 
 
 
Number of games played (current opponents): 273 (updated: 2016/12/14)
 
Download all played games [You must be registered and logged in to see this link.]
 
Current participants: Stockfish 8, Komodo 10.2, Houdini 5. Contempt set to +15 (means: Contempt=1 for Houdini 5 (!!!)) for all engines.
I decided, to play only with the "big three" and take Shredder 13 out - Shredder is too weak.
